Oddly enough, the 14902 I owned at one point did not lack the "officially certified" and had a higher serial number... So it's possible that the movement on either watch has been replaced
That dial is lovely, btw. It's the same as on my 14902 and I've never seen a photo that could do it justice. Simply superb.
